Maps for a Better Lake Michigan
We’re diving deeper to improve the world’s largest freshwater system – beginning at home in the Milwaukee Harbor. Mapping fish habitats helps protect and restore vibrant wildlife populations in the heart of urban Milwaukee.
Charting Life Under Water
Researchers from the School of Freshwater Sciences mapped 42 miles of Milwaukee’s lower estuary, where Lake Michigan meets the city’s southern waterways, to find the homes of freshwater fish. Designed by Associate Professor Kim Beckmann, the resulting maps show wildlife teeming below the surface of this industrial harbor. The maps are educating the public and supporting clean-up efforts throughout the area, as activities are underway to connect and expand the “habitat hotspots” researchers discovered.

How Maps are Helping Restore the Harbor
The Milwaukee Harbor is an EPA “area of concern” because of its high levels of industrial waste. As governmental agencies, researchers and nonprofits seek to get our harbor off that list, the maps on this page help them identify which interventions will be most effective. The harbor maps also spurred the creation of a consortium of organizations that can take on large-scale improvement projects and fueled additional grant proposals to map more areas and expand habitats. Finally, the maps are being distributed to the public to inspire residents and visitors to be stewards of our local ecosystem.
Future Maps
With the Milwaukee Harbor Mapping project moving into the graphic design phase, the Fund for Lake Michigan funded a second mapping project. This new project focuses on mapping fish spawning and foraging habitat in the Lake Michigan harbors of the Wisconsin communities:
- Algoma
- Kewaunee
- Two Rivers
- Manitowoc
- Sheboygan
- Port Washington
- Racine
- Kenosha
Each of the four harbors is smaller than the Milwaukee Harbor, with smaller river input. The diversity of size of the several proposed harbors along with Milwaukee affords an opportunity for deeper understanding of how these “manufactured” ecosystems function. Each harbor at its current state has lost its original coastal wetland due to conversion of multiple purposes with significant industry influence. The maps will help stakeholders in each community to enhance ecosystem services so that diverse recreational opportunities—and a recreational economy—can flourish alongside the industries that employ area residents.
The project began in 2018 and is currently ongoing. As with the Milwaukee Harbor project, both technical Graphical Information System (GIS) maps and more accessible public maps will be produced.
